Your lesson.

LitBook is an AI language-learning app that generates short reading passages at exactly your level. Every lesson is an original passage on a topic you chose, followed by eight questions — grammar, vocabulary and reading comprehension — with hints in your own language and instant feedback.

Yes. The free plan includes 30 credits every month — enough for a short reading lesson a day. Paid plans with more credits and read-aloud audio are on the way.

French, Spanish, English, German, Italian and Swedish — each at any CEFR level from A0 (absolute beginner) to C2.

None. LitBook starts at A0 with tiny present-tense sentences built from the few hundred most common words, and you can change your level anytime as you improve.

Duolingo is built around gamified micro-drills; LitBook is reading-first — the whole lesson is a passage written at your level, with comprehension checked and your missed words recycled into future passages.

Yes. Generated lessons are saved as drafts, and your answers are autosaved so you can continue on another visit or device.

Every lesson passes structural, level and passage-grounding checks, then an independent reviewer checks grammar, clarity and answerability. If a lesson still fails after one repair attempt, LitBook blocks it and refunds the credits instead of showing it.

Research consistently shows that large amounts of reading at a level you ~98% understand is one of the most effective ways to acquire vocabulary and grammar naturally. LitBook exists to keep you at that exact level.
